Every time I try to remove it it crashes chrome. Doesn't do it with any other extension. Seems like a virus

Doesn't work at all noting pops up, noting opens up and can't find it on the right click mouse menu either. I'm using Brave browser, fix this please! I want to be able to view source code and copy it like everyone could years ago,it's the best way to learn how to code this new stuff that's out now.

Downloaded zip file can't be installed by chrome. Not working as expected. Using "Give Me CRX" instead, which works.

Not working any more, icon always remains discoloured no matter which extension I visit. Probably new website chromewebstore.google.com is the reason.

This extension conflicts with GMail that when it's enabled, you can't do copy paste from the address line.
